Nivolumab treatment in a mucosal melanoma patient with pre-existing systemic lupus erythematosus: A case report with literature review

Abstract

Introduction. Systemic lupus erythematosus (SLE) represents a multisystemic disease characterized by antibody production, complement activation, and immune complexes deposition. Certain types of malignancies occur more often, and conversely, some of them occur less often in SLE patients. Mucosal melanoma of the anorectal region represents a rare form of melanoma occurring in 1.5% of all melanoma patients, predominantly female. The introduction of novel agents dramatically changed the outcome in melanoma patients and introduced different adverse events, diverse contraindications, and drug interactions. Immune checkpoint inhibitors have a role in the maintenance of immunologic homeostasis. Patients with underlying autoimmune diseases were often excluded from clinical trials, for fear of possible autoimmune disease exacerbation or high-grade immune-related adverse events. Due to that, data regarding this subgroup of patients is limited, with no clear recommendations. Given the fact that prevalence among the general population is high (5-10%), autoimmune diseases represent common comorbidity in cancer patients. Having that in mind, it is of utmost importance to personalize the approach and individualize the SLE treatment and enable the use of PD-1 antibody in the safest and most useful way while keeping the SLE in control. Case report. Herein we present a 79-year-old with primary mucosal melanoma of the anorectal region, with lung metastasis and preexisting SLE in remission. Hydroxychloroquine was the only treatment for SLE. Nivolumab treatment was initiated in the standard dosing schedule. After the first and second follow-up, no further progression of melanoma was detected, with no SLE exacerbation and immune-related adverse events. Conclusion. PD-1 treatment in a patient with an underlying autoimmune disease represents a viable choice with a necessity for a multidisciplinary approach and close monitoring.
